This release of i1Match is currently not able to create correct large ICC4 monitor profiles on the new Intel Macs. It is recommended to create only default monitor profiles on the Intel Macs until a new version of i1Match will be released.*

At the time this release note was written, the issue was not fully understood. As it happens, the issue with version 4 profiles was caused by a bug in ColorSync in the initial release of Snow Leopard. Apple responded quickly to the issue which was addressed in the OSX 10.6.2 update. i1Match does indeed build good version 4 ICC profiles on OSX 10.6.2 and 10.6.3, with preferences set to LUT (large) or matrix (small).
